Rosencrantz & Guildenstern Are Dead. Perhaps no plat has passed so quickly into the standard repertoire as Tom Stoppard's early masterpiece. If you've never seen it, you own yourself a treat, like the first time you read Lewis Carroll or Evelyn Waugh. R & G is an actor's showcase, and if the eponymous reads are any good-you should laugh from the beginning until the surprisingly, tender conclusion. The play is about two characters in search of a language and contains the most brilliant wordplay on the English stage (always rich in wordplay) since Shakespeare or at least Wilde. The "Questions" scene ("None sequitur. Thirty love.") is alone worth the price of admission. At the Loeb mainstage tonight, tomorrow, Saturday and Sunday as well as next weekend. 8 p.m.

Orphous at the Loeb Ex Thursday, Friday, and Saturday at 7:30 p.m. Joan Cocteau's best, perhaps, Reviewed in today's Crimson.

The Conci is reviewed in today's Crimson. Artaud's Theater of Cruelty is an ambitious production that achieves a lot, though there are problems. Dudley House tonight through Saturday at 8 p.m.

Put Up Your Dukes. I can't think of anything funny to say about this landmark in the history of Western thought this week. At the Hasty Pudding through the end of the month.
